Subsequent development efforts, led by Michael White,
have focused on making the realizer practical to use in dialogue
systems, and more recently, on realization with broad coverage
grammars. See the papers on Mike's web page for details. Since
version 0.9.4, OpenCCG has included broad coverage English parsing and
realization support that together make it possible to experiment with
open domain grammatical paraphrasing. Version 0.9.5 adds features for
dependency ordering and dependency length minimization in realization,
as in White and
Rajkumar (2012), along with support for using 5-gram gigaword
language models with KenLM, and creating
disjunctive logical forms based on the differences between aligned
semantic graphs, as in Martin and
White (2011). It also includes ccg2jsgf, an extension
developed for Knexus Research Corporation for compiling an OpenCCG
grammar into a context-free grammar in the Java Speech Grammar Format
used by the Sphinx speech recognizer, now released open
source. (new!)

Also, Jason Baldridge and students at UT Austin have developed DotCCG,
a new format for specifying OpenCCG grammars, and VisCCG, an editor
and visualizer for grammars written in DotCCG format. These
developments are described in Baldridge,
Chatterjee, Palmer and Wing (2007). See the UT Austin
computational linguistics lab's OpenCCG
wiki, which has a number of tutorials and example grammars for
DotCCG and VisCCG.
